10 SEBAB KENAPA KOMPUTER ‘HANG’

Kemungkinan selepas setahun kita menggunakan komputer, kita akan dapati terdapat beberapa perubahan yang ketara terhadap prestasi komputer kita misalnya selalu ‘hang’ ataupun operasi yang semakin lambat. Jika kita pengguna yang hardcore pula, masalah ini pasti berlaku lebih awal lagi. Berikut disenaraikan sepuluh perkara yang dirasakan menjadi punca kepada terjejasnya prestasi komputer kita.

d

1. MIKROPEMPROSES MENGALAMI KEPANASAN MELAMPAU.

Kepanasan melampau ini terjadi apabila motor kipas yang menjadi penyejuk kepada mikropemproses tidak dapat berfungsi dengan baik. Ini disebabkan habuk yang terdapat di sekeliling kipas yang menyekat putaran kipas tersebut. Selain daripada itu, mungkin bearing kipas menjadi longgar yang menyebabkan gegaran berlaku pada mikropemproses. Kesannya ialah mikropemproses tidak dapat bekerja dengan baik.

2. MASALAH RAM

Terdapat juga RAM yang dari jenis murah yang tidak memenuhi spesifikasi serta mempunyai masalah komposisi cip-cip yang siap terbina. Akibat dari masalah ini, ialah RAM mudah mengalami kepanasan melampau yang menjejaskan keupayaan komputer. Selain daripada itu, masalah ëBlue Screení juga akan lebih kerap berlaku.

3. CAKERA KERAS

Bagi cakera keras pula, masalah-masalah yang menyebabkan terjejasnya prestasi komputer ialah seperti bertambahnya sektor-sektor rosak (bad sector) ketika melakukan proses chkdsk dan scandisk, kerosakan dalaman (intermittent) yang mengakibatkan kegagalan proses boot dan capaian putaran per masa yang rendah yang mungkin tidak sesuai dengan spesifikasi komputer yang digunakan.

4. KONFIGURASI BIOS

Pengguna komputer seharusnya tidak terlalu bergantung kepada konfigurasi BIOS ‘kilang’ sebaliknya perlu mengetahui konfigurasi sistem yang optimum. Ini adalah kerana konfigurasi BIOS yang tidak tepat turut mempengaruhi keupayaan komputer.

5. PENGAWAL CAKERA

Kabel pengawal yang digunakan perlu menepati spesifikasi pengawal cakera yang dipasang. Begitu juga dengan papan ibu (motherboard) yang harus mampu menyokong pengawal cakera. Sebagai contoh pengawal cakera UDMA-66 memerlukan kad khusus untuk dipasang pada papan ibu yang hanya menyokong pengawal cakera UDMA-33. Jika tidak dipasang, ia pasti akan mengundang masalah kepada prestasi komputer.

6. SISTEM OPERASI

Sistem operasi seperti Windows XP dan Windows 2000 biasanya mempunyai banyak servis yang dijalankan. Servis-servis yang dijalankan jika terlampau banyak akan merencatkan prestasi komputer. Servis yang jarang diguna sepatutnya diberhentikan kerana ia banyak menggunakan sumber tenaga komputer.

y

7. PROSES DAN APLIKASI

Proses dan Aplikasi (.exe) yang terlampau banyak digunakan akan menyebabkan komputer menjadi perlahan. Untuk melihat proses dan aplikasi yang sedang dilarikan, pengguna bolehlah klik pada bahagian Windows Task Manager.

8. FRAGMENTASI CAKERA

Fragmentasi cakera berlaku apabila terlalu kerap fail-fail disimpan, dipadam dan ditukar. Ini menyebabkan kandungan fail bertaburan didalam sektor. Fragmentasi juga berlaku apabila kandungan cakera penuh. Seharusnya ruang kosong sebanyak 20% sehingga 25% perlu disediakan bagi mengurangkan masalah fragmentasi ini.

9. APLIKASI LATAR BELAKANG

Ramai pengguna yang suka melarikan aplikasi latar belakang secara automatik selepas proses boot ataupun permulaan sistem operasi. Aplikasi yang terlalu banyak dilarikan pada satu-satu masa akan menyebabkan komputer menjadi perlahan dan adakalanya menyebabkan ‘hang’. Aplikasi-aplikasi yang digunakan ini boleh dilihat pada folder Startup.

10.SISTEM FAIL

Dalam sistem operasi Windows terutamanya NT dan 2000, pemilihan sistem fail iaitu NTFS dan FAT adalah sangat penting. Ini adalah kerana sistem fail ini merujuk kepada saiz dan bilangan kelompok dalam sesuatu cakera. Saiz kelompok yang besar akan meningkatkan prestasi komputer. Kebiasaanya, sistem fail NTFS mempunyai saiz kelompok yang lebih besar berbanding FAT.

Namun, antara semua masalah yang ada ini dapat di atasi dengan cara anda lakukakan penyelenggaraan kerap terhadap komputer anda. Penyelenggaraan anda boleh lakukan samada menggunakan apa-apa software yang berkaitan atau anda boleh hantarkan kepada kami untuk lakukkan penyelenggaraan. 

Akan datang saya akan kongsikan tips dan cara bagaimana untuk lakukan penyekenggaraan sendiri. Ya! anda boleh lakukan penyelenggaraan asas komputer anda. Hanya sedikit teknik dan keberanian..hehe..

Nantikan post saya yang akan datang..

Selamat pagi semua. .
 
#tips hari ini ialah… #antivirus
 
.
.
 
Kenapa saya kata jangan pakai antivirus? Mesti anda pelik kn. Kerana sebelum ini semua cakap pakai antivirus, tapi saya kata jangan pakai antivirus pula.
 
Anda jangan pakai antivirus jika anda tidak tahu pakai antivirus. Betulkan apa yang saya kata?
.
.
Anda beli antivirus mahal2. Anda bayar pada kedai untuk install kan software tersebut. Kemudian anda mengharap komputer anda tidak dijangkiti atau diserang virus. Manakala si penjual pula langsung tidak berikan nasihat penggunaannya dan berseronok dengan duit hasil jualan itu. Akhirnya komputer anda tetap kena virus..siapa yang rugi?
.
.
So, lebih baik anda jangan pakai antivirus. Anda jimat, dan tidak buat dosa kerana mengutuk atau memaki penjual tersebut. ..hehehe..
.
.
Siapa yang salah?
.
Ok lah. Saya tidak mahu menyalahkan sesiapa walaupun anda ada hak sebagai pengguna untuk memastikan cara ppenggunaan dan bertanya.
.
Saya ingin maklumkan pada anda semua, jika anda membeli atau hanya menggunakan antivirus yang free use seklaipun, ianya tiada masalah. Yang penting ialah cara menggunakan antivirus tersebut dengan berkesan.
.
.
1. Auto update : Setelah anda install antivirus, pastikan ia di setting auto update. Maka,setiap kali komputer anda connect ke internet ia akan auto update latest virus definition.
.
2. Real-time scan: Pastikan setting Real-time scan dihidupkan. So,komputer anda akan protected 24/7. Tapi,ini yang selalu menyebakan ramai user kena virus. …
.
.
Bagaimana cara mengatasinya??? Nanti saya share semula. Ada pelanggan datang,saya hendak pergi layan pelanggan dulu.
.
.
p/s: Share jika anda rasa bermanfaat. tq.

Have you ever run out of battery power on your laptop, notebook, or netbook during a meeting or a class? Sufficient battery life is a persistent challenge for mobile PC users. You can take simple maintenance steps to extend the life of your laptop battery. The Windows operating system also offers several ways to help maximize the battery life of your mobile computer.

In this article, I’ll introduce some tips that you can use to recharge a battery and extend laptop battery life, and I’ll discuss how to take advantage of Windows settings to manage power more efficiently.

 

Treat your battery right

For on-the-go computing, your battery is your best friend. Knowing how it likes to be treated is the first step to keeping both of you happy.

  • Keep battery contacts clean. Battery contacts can get dirty or corroded over time, reducing the effective delivery of power. With your mobile PC turned off and unplugged from its external power source, remove the battery. Use a cotton swab dampened with rubbing alcohol to wipe the metal contacts on the battery and inside the device. Allow them to dry completely before reinstalling the battery and reconnecting to a power source. Repeat this procedure every two to three months.

  • Charge your battery correctly. When you’re on the road, be sure to carry a power cord and plug your computer in whenever you have the chance. Unlike the older-generation rechargeable batteries like nickel-based (NiMH) batteries (see next paragraph), modern lithium ion batteries can be partially discharged and recharged repeatedly with no harmful effects, but you should avoid fully discharging lithium ion batteries. Consult your owner’s manual for more specific tips on charging, and never use an AC adapter (power cord) or battery charger not approved by your device’s manufacturer.

  • Completely drain nickel-based batteries periodically. If you’re using an older laptop (at least three years old) with a nickel-metal hydride (NiMH) battery, be sure to completely drain it and recharge it (every one to three months—consult your owner’s manual) to ensure that it will hold a full charge. (Most newer mobile PCs use lithium ion batteries, which don’t need to be drained to maximize their capacity.) To drain a NiMH battery, simply turn on your computer, unplug it from its external power source, and let the computer run. To speed things up, you could start several applications, turn the screen brightness to its highest level, and ignore all of the great power-saving strategies below. After the power is completely drained, recharge the battery fully. This may take up to 12 hours.

  • Cool it. Your mobile computer generates heat, and higher operating temperatures reduce your device’s efficiency, which in turn demands more battery power and can shorten battery life. Make sure that your computer can “breathe”: Don’t let clothing, lint, or other obstructions block the cooling vents. See How to clean your computer for more tips on keeping your computer spotless and running smoothly.

  • Carry a spare. Buying an extra battery is a good investment for your peace of mind. Battery prices vary widely. You can significantly increase the power available to you if you’re willing to splurge a little. Contact the manufacturer of your mobile PC to find a replacement battery, or search here.

  • Store it properly. If you don’t expect to use your mobile computer for a week or more, it’s a good idea to store the battery, discharged to about 40 percent of full capacity, in a cool place. Click the battery status icon in the notification area of the Windows taskbar to check the current charge. Avoid storing a fully discharged—or fully charged—lithium ion battery for extended periods, as this can diminish battery life.


 

Optimize your power settings

The display and hard disk on your mobile PC are the two biggest consumers of battery power. By choosing a power plan (called a power scheme in Windows XP) you can extend your battery life by automatically lowering screen brightness and reducing other power-hungry functions. A power plan is a collection of hardware and system settings that control how your mobile PC manages power.

 

Windows 7

Windows Vista

Windows XP

 

You can also create a custom power scheme to suit your specific needs. You can create as many custom power schemes as you want.


 

Take advantage of low-power states

The different versions of Windows provide the following battery-saving states:

  • Windows 7. Sleep and hibernation (which is like deep sleep)

  • Windows Vista. Sleep and hybrid sleep (which is a combination of sleep and hibernation)

  • Windows XP. Standby (which is like sleep) and hibernation (which is like deep sleep)

Sleep (Standby)

In a sleep state (standby), your display and hard disk turn off, and all open programs and files are saved in random access memory (RAM)—your computer’s temporary memory—rather than to the hard disk. Information stored in RAM is cleared when the computer turns off, so it’s a good idea to save your work before placing your system in sleep or standby mode. Otherwise you may lose data if you lose power or swap batteries or if your system crashes.

Sleep (standby) is particularly useful when you’re using your mobile PC intermittently during the day. For example, when driving between clients’ offices, put your computer to sleep or on standby to maximize the life of your battery and to maintain quick access to open programs, files, and documents. When you want to use your computer again, it wakes up quickly, and your desktop is restored exactly as you left it.

 

Windows 7

Windows Vista

Windows XP

 

Hibernation

In hibernation, your computer saves everything to your hard disk and then shuts down. When you restart the computer, your desktop is restored exactly as you left it. Hibernation uses less power than the sleep state (standby), but it takes a bit longer to resume.

 

Windows 7

Windows Vista

Windows XP

 

Hybrid Sleep

Hybrid sleep is a power-saving feature designed primarily for desktop computers. Hybrid sleep saves any open documents and programs to random access memory and to your hard disk and then puts your computer into a low-power state.

  • Find out more about hybrid sleep in Windows 7.

  • Find out more about hybrid sleep in Windows Vista.


 

Adjust screen brightness

You can also conserve battery power by reducing the screen brightness. To adjust your screen brightness, refer to the instructions from your mobile PC manufacturer. Every computer is slightly different, but you can usually use a combination of keys, a function key, or a software tool to dim the screen.

Even better than dimming the screen is blanking it completely when you’re not using your computer. You can further minimize power consumption by reducing the amount of time the computer is idle before the screen goes blank. The power schemes and power plans in Windows let you adjust your power settings to turn off the display after as little as one minute of inactivity. In addition, a number of third-party software developers offer free applications that enable you to turn the display off and on at will.


 

Turn off wireless

Another significant drain on your battery power is your wireless card. You should turn off your wireless device when you’re using your mobile PC but are not connected to a wireless network. You can either remove your Wi-Fi card or press the manual hardware button (or switch) on your computer, if you’re using a Centrino-based mobile PC. Refer to the instructions from your mobile PC manufacturer to learn where the manual hardware button is. Other computers may require that you turn off the wireless connection using software settings. Again, consult your instruction manual for details.


 

Additional power-saving tips

In addition to adjusting power settings to maximize battery life, consider the following tips to minimize power consumption when you’re away from electrical outlets.

  • Turn off scheduled tasks. If you use scheduled tasks to run programs or scripts, or if you schedule other tasks to occur automatically at a preset time, specify that these tasks won’t be performed when the computer is running on battery power.

  • Keep the use of tools in the notification bar to a minimum. Try to minimize your central processing unit (CPU) usage. Look at the notification area of the taskbar and close any tools (or utilities) that are not necessary. Often, these tools are installed on the computer when you first receive it. Windows 7 users can also click the up arrow at the end of the notification area to see tools and utilities that are hidden but available. The notification bar, shown below, is on the bottom right of your computer desktop.

  • Limit power-intensive activities. Avoid watching a DVD, listening to a CD, or playing online games on your mobile PC when you need to conserve battery power.

  • Add memory. You can minimize the reliance of Windows on virtual memory and reduce power consumption by adding memory (RAM) to your mobile PC. (Shop for additional memory.)

By adjusting your mobile PC settings to conserve battery power and by implementing these tips, you can relieve the stress and inconvenience of running out of battery power.
